Is Xayah see Ahri as betrayal because she has relationship with human?

In Xayah's taunt she called Ahri a traitor. If Ahri has relationship with human, is can be reason for make she become Xayah's rivalry? Because if Ahri has relationship with human, she will not let Xayah kill a human who became friend with her.

But Ahri never s relationship with human, why Xayah become Ahri's rivalry? If Ahri doesn't have relationship with human, should Xayah negotiate her and hunting humans together?

For me if Xayah called Ahri a traitor. I doubt Ahri already have human friend with her but don't reveal yet.
